I am using Mr Gasket copper on my Hedman Elites. These headers have 3/8 flanges. Not familiar with the super comps.

Super Comps have a thinner flange. (1/4"?)
I used Percy's Dead Soft aluminum gaskets on my Hedman Elites... 10 years ago.
I haven't noticed any leaks yet!

The thick, multi-layer design seems to compress nicely and creates a good seal.

I also used multi layered soft aluminum and that was 3 years ago-no leaks

Soft Aluminum for head to headers and Remflex for flange.

Mr Gasket is a solid copper. The indentation around the port makes for a good seal.https://www.holley.com/products/gaskets/header_gaskets/parts/7153

Since you have Vortec heads... I would go with the 760-66121. (They specifically mention "Vortec".)

I think I used the 760-66011 for standard old-school small block heads.
It's been a decade... I would have to search my project thread and maybe come up with a number which won't be specific for your application.

Hop to it, Harry!
